Stress state in the process of deep drawing of sheet metal cover as a part of a clutch cover for commercial motor vehicles

The object of this paper is a sheet metal cover from diaphragm frictional clutch cover MF 395, made form sheet metal with thickness of 5mm. Using numerical simulation and experiments, the stress distribution was determined in the technological process of the first deep drawing operation. The numerical simulation was performed using the software Simufact and the stress was determined by applying deformation analysis. A comparative analysis was made between the experimentally obtained results and the ones determined by numerical simulation
